The main and most essential element of the door, affecting the safety and appearance both in the apartment and in the office or other premises, is the lock. When choosing a door, we pay no less attention to the keyhole than to the door plane. The key element is the lock cylinder. Other names for this element often include names such as "core", "core", "larva" and "secret" of the lock.

How to choose a cylinder?

What should you first of all pay attention to when buying, how can an ordinary buyer choose according to the "price-quality" parameters? Before answering these questions, give a definition of what is a lock cylinder?

The cylinder mechanism has a number of advantages. The main one is compact size and the ability to replace only the core without replacing the rest of the structure. For more than a hundred years of its existence, such a system has become the most reliable and convenient of all locking indicators.

The structure of the lock core consists of spring-loaded pins, plates of different sizes, balls. For this design, flat keys with teeth (notches) on one side – English, or projections in the form of dots - with a laser pattern or perforated are used.

When choosing, each customer is guided by his own needs, which the lock cylinder must meet - ergonomics, reliability, safety.

Depending on the locking method and sides, the following types of larvae are distinguished:

On both sides with keys;
On both sides with a key and a handle;
One-sided with a key;
On one side with a handle.

The cores differ into the following types:

With a disk mechanism, as a rule, it has a low level of secrecy and is distinguished by a significant proportion of low-quality or defective larvae that are not able to work for a long period. The device with a disk mechanism is semicircular and has the appearance of a round bar sawn along.
With a cross pin (pin), they are small in size and are located in three planes of the cylinder. Based on the design, 4-row pin placement is also possible. The hole and key are cruciform. This type is also distinguished by a not very high level of burglary security, inconvenience in operation, and poor quality material.
With a pin device, there are many varieties and may contain an electronic or magnetic element.

Features of cylinders

Depending on the location of the pins and the shape of the key mark itself, cylinders are distinguished with the so-called "English" and with a perforated (small notches laser).

Locks with an English cylinder are more likely to be broken, as they contain a low level of security. There are many ways to hack, the most common is a master key or a forceful method.

Some producers have English larvae with maximum protection, reinforced with floating magnets, diamond-head and horizontal pins. However, these lock cylinders can be quite expensive.

Laser-cut cores have a higher degree of protection, which have a high resistance to burglary and a more reliable level of secrecy. This structure is also equipped with some protection against bumping, picking or pulling the lock.

Perforated with a laser cut have recesses on the key in the form of holes, according to the number of pins in the larva.

Such mechanisms have additional levels of protection – the arrangement of telescopic pins in several rows, planes, additional recesses (tracks) on the key, magnets or electronic components (for example, Mul-t-lock).

When choosing and ordering a product, the buyer is guided by his preferences, depending on the specific situation and cost.

Advantages of lock mechanisms

Match the device and the cylinder to it from the same quality and price categories. This is due to the fact that the cost and safety indicators are leveled by a not very high-quality design.

The main indicators that the consumer is guided by when choosing a castle larva are:

Wear resistance – workmanship, material, manufacturer.
Safety – the degree of protection, from drilling, opening, knocking out.
Cost – as a rule, they choose products with the optimal combination of quality and price indicators.
Key ergonomics – configuration and usability.
Appearance – basically the choice was made in favor of those in harmony with the door in which it will be installed.

The lock cylinder has an average price and meets the basic requirements of safety, quality and ease of use.
